User manual - METER SWE-73-L
“Lo C”
“Hi C”
These parameters describe the values displayed for minimum and maximum input
current.
“Lo C”
parameter defines the value displayed when input current is equal
4 mA, and
“Hi C”
parameter defines the value displayed for 20 mA of input current.
Available range for these parameters: -999 ÷ 9999. Negative values can be set by
entering
'-'
sign on the first position (by use of
[^]
,
[v]
buttons).
If user defined characteristic is selected
(parameter
“CHAr”
=
“USEr”
) the
parameters
“Lo C”
and
“Hi C”
are not available for modification, due to their values
are calculated from defined characteristic.
“AddP”
- this menu allow user to add single point to the user defined characteristic.
After selection of this option device waits for
“X”
and
“Y”
coordinates of new point.
Modification of the coordinates is done accordingly to numerical parameters edition.
Coordinate
“X”
defines the percentage ratio of input current to selected current
range. The
“X”
range: -99,9 ÷ 199,9. Coordinate
“Y”
defines displayed value for
particular
“X”
value. The
“Y”
value can be changed in range: -999 ÷ 9999, decimal
point position depend on
“Pnt”
parameter (menu
“inPt”
).
•
User can not enter two points with the same value of
“X”
coordinate. If user
trays to do it,
“Err”
warning is displayed. To modify any defined point use
“EdtP”
option.
•
To distinguish
“X”
and
“Y”
coordinates, if
“X”
coordinate is displayed an
additional decimal point on utmost right position is displayed.
•
If user defined characteristic is selected, and if number of defined points is lower
than 2 then warning
“Errc”
is displayed in measurement mode.
“dELP”
- this option allows user to delete any of the points of the user defined
characteristic. After selection current number of points of the user defined
characteristic is displayed for about approx. 1.5 sec. After that device waits for
selection of point being deleted (by
[^]
,
[v]
buttons). The short pressing of
[ENTER]
button causes by switching between
X
and
Y
value of the displayed point. The long
press (press and hold at least 2 sec) of
[ENTER]
button causes by displaying
“dEL?”
ask. If
[ENTER]
button is pressed again, current point is deleted and new
updated number of points of the user defined characteristic is displayed.
“EdtP”
- this option allows user to modify of particular point of the user defined
characteristic. After selection current number of points of the user defined
characteristic is displayed for about approx. 1.5 sec. After that device waits for
selection of point being edited (by
[^]
,
[v]
buttons). The short pressing of
[ENTER]
button causes by switching between
X
and
Y
value of the displayed point. The long
press (press and hold at least 2 sec) of
[ENTER]
button causes by entering to edit
the selected coordinate of the point. Modification of the coordinates is done
accordingly to numerical parameters edition.
“AddP”
,
“dELP”
and
“EdtP”
options are available only if the user defined
characteristic is used (it means when parameter
“CHAr”
=
“USEr”
).
“Lo r”
,
“Hi r”
- these parameters define the expansion of nominal range in percent. They
determine the permissible range of input signal (figure 7.1).
